VEHICLE POL E AND COUPLING.

SPECIFICATION forming part of Letters Patent No. 570,020, dated October 27, 1896.

Application filed November 26, 1895. Serial No. 570,164. (No model.)

To all whom it may concern:

Be it known that I, JOSEPH IMLER, a citizen of the United States, residing at Kendallville, in the county of Noble, State of Indiana, have invented certain new and useful Improvements inVehicle Poles and Couplings, of which the followingisaspecificationn'eference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in poles and couplings of that class constructed of tubular material; and it has for its object, among others, to provide an improved, simple, light, and cheaply-constructed and durable pole and coupling, the parts of which may be readily assembled and which are so constructed as to combine strength and lightness. I provide novel means for the connection of the singletree or doubletree, permitting only a limited movement thereof. I also provide novel means for bracing the pole and for swiveling the neck-yoke.

Other objects and advantages of the invention will hereinafter appear, and the novel features thereof will be particularly pointed out in the appended claims.

The invention is clearly illustrated in the accompanying drawings, which, with the letters of reference marked thereon, form a part of this specification, and in which Figure 1 is a top plan of my invention. Fig. 2 is a detail in side elevation. Fig. 3 is a top plan of a pole and its attachments embodying my invention. Fig. 4 is a side elevation of Fig. 3 with the whiffletree in section. Fig. 5 is a detail partly in elevation and partly in section, showing the manner of swiveling the neck-yoke. Fig. 6 is an enlarged detail, partly in elevation and partly in longitudinal vertical section, showing the manner of attaching the singletree or doubletree. Fig. 7 is a horizontal section on the line 7 7 of Fig. (5, looking in the direction of the arrows.

Like letters of reference indicate like parts throughout the several views.

In carrying out my invention I construct the shafts A of gas-pipe or tubular metal, the rear ends of which are screwed into the Ts A, in the opposite ends of which are supported the rear tubular parts A which have the required curvature and are adapted for attachment in the usual manner, while in the adjacent necks or nipples a ofthe Ts are held the tubular parts A which are threaded into the coupling A which, together with said parts A A constitutes the cross or connecting bar of the thills. This coupling A has an upwardly-extending portion or neck a, as seen best in Fig. 6, and which, as seen in Fig. 7, has a rectangular opening a, into which extends a rectangular boss or depending portion I) of the coupling 13 of the singletree, which is composed of the two tubular parts B, the ends of which are screw-threaded into said coupling, as seen best in Fig. 6. A bolt 0 passes through a vertical opening in this coupling and in the boss 1) thereof through the coupling A and receives upon its lower end a nut G, by which the parts may be connected together. By this construction the singletree may move freely within prescribed limits, but cannot move in either direction beyond a fixed point determined by'the movement of the boss within therectangular opening of the coupling. Upon the under side of the shafts I attach spring-holdbacks D, consisting each of a single piece of spring metal secured at one end and the other free, as indicated in Fig. 2.

In Figs. 3 and 4 I have shown a pole embodying the same features above outlined in connection with the thills, the doubletree being constructed and mounted in a similar manner to the singletree seen in Figs. 1 and 6 and the whiffletrees mounted upon the doubletree in substantially the same manner.

E is the pole; -E, the'doubletree; 6, its coupling; 6, its bolt, and E the coupling into which the pole is screwed and which is the equivalent of the coupling A in Fig. 1.

The singletrees are similar in construction and manner of mounting to the singletree seen in Fig. 1, and a detailed description thereof is not necessary.

From the rear end of the coupling E ex- 9 tends a short pipe F, engaged in the nipple f of the T F, in the opposite ends of which are secured the tubular curved piecesF The rear ends of the curved pieces F are each held in a coupling'G, in the outer end of 100 which are the pieces G, designed for attachment in position in any suitable manner. The couplings G have upon their under sides the downwardly and forwardly curved nipples or couplings g, in which are secured the tubular braces 11, preferably in two parts, as shown, connected by a coupling h, whereby they may be readily separated when desired, the other ends of said braces being engaged in the downwardly and rearwardly curved nipples or couplings 1, extending from the coupling E as seen in Figs. 3 and it, the said braces H diverging from their point of attachment with the couplings I I, as seen best in Fig. 3, so as to give great strength to the pole.

InFig. 5 I have shown a neck-yoke composed of the coupling J and the tubular pieces J, screwed therein, as shown. This coupling has an openingj in its upper portion and on its lower face a boss j,through which passes the vertical shank of the T K, the horizontal portion of which T is engaged in the fold of the leather piece K, having an opening 70 to receive the pole in the usual manner. In applying this leather to the neck-yoke the vertical portion of the T, which is passed up through an opening in the leather, is inserted in the boss of the coupling J and riveted bya suitable tool placed through the openingj in the upper face of said coupling, as will be readily understood from Fig. 5, so that the neck-yoke is mounted to swivel on the said T and the headed portion of the shank is eonfined within the coupling.

Modifications in detail may be resorted to without departing from the spirit of the invention or sacrificing any of its advantages.

The whiftletree and doubletree connections may be shrunk on instead of being threaded, and, as seen in Fig. (5, a washer L may be employed between the conncction-for instance, as between the neck a and the coupling B, around the depending portion 1) thereof-to prevent rattling.

lVhat I claim as new is 1. The combination with a coupling having a boss with a rectangular opening, of a coupling having a rectangular boss working in said opening, and a bolt passed through the two couplings to connect the parts together, substantially as specified.

2. The combination with a coupling having a boss with a rectangular opening, of a coupling having a depending rectangular boss arranged in said opening, a bolt passed vertically through the two to unite them, and

tubes held in opposite sides of said coupling, substantially as specified.

The combination with a coupling having tubular necks at its opposite ends and a boss and an opening in its upper face in line with said boss, the tubular portions detachably engaged in said necks of a stud passed through the boss and headed within the coupling and having a horizontal portion outside the coupling, and the pole attachment held on said horizontal portion, substantially as specified.

4. The combination with the pole and the coupling at the rear end thereof having curved and downwardly and rearwardly extending nipples, and the rearwardly-extending T- coupling of the curved tubular parts supported from said T'coupling, couplings on the rear ends thereof having curved downwardly and forwardly extending nipples, and the brace-rods connecting the said nipples with those on the coupling at the rear end of the pole, substantially as specified.

5. The combination with the pole and the coupling at the rear end thereof havin g curved and downwardly and rearwardly extending nipples, and the rearwardly-extending T- coupling of the curved tubular parts supported from said T-coupling, couplings on the rear ends thereof having curved downwardly and forwardly extending nipples, and the brace-rods connecting the said nipples with those on the coupling at the rear end of the pole, said brace-rods being formed of tubular sections, substantially as specified.

6. The combination with a coupling having tubular screw-threaded necks at opposite ends and a boss extending at right angles to said necks and provided with a rectangular opening, of a coupling having a rectangular boss working in said opening, a bolt passed through the two couplings to connect the parts together, and a washer around the rectangular boss and between the coupling and the upper face of the neck in which said boss works, substantially as specified.

In testimony whereof I atlix my signature in presence of two witnesses.

JOSEPH IMLER.
